Data in the employment section is drawn from BLS State and Area Employment files, which draws from the Current Employment Statistics survey (also known as the establishment survey). To avoid issues of seasonality, the data are presented annually for each year, except for 2014 where August was the most recently available data). Detailed description of the data available here: ftp.bls.gov/pub/time.series/sm/sm.txt
Data in the income section is drawn from two sources. Median and mean household income data come from the American Community Survey 1-year files for 2007-2013. Personal income per capita comes from BEA regional data. The updated data for 2014 was not available until late November, so this report includes mean and median household income from the ACS for 2013. Note that differences exist in observed income between Census Bureau and BEA data. The differences between median household income and personal income per capita reflect a variety of factors, including growing income inequality, changing demographics, differences in unreported income, and different definitions of income.1 GMP data was drawn from the Brookings Institutionís Metro Monitor September 2013 update, available at: www.brookings.edu/research/interactives/metromonitor. 1
